Figure 8Measured data showing the decay in the IP and the fitted decay times in blue. The fitted parameters have the following values: A = 0.36, B = 0.64, 1 = 14.9 min and 2 = 434 min. The plot furthermore illustrates a virtual example, where the IP is exposed for 8 min (red), waiting for 10 min and developed for 4 min (black). The correct decay correction is explained in the main text.
